     - all (array) (first 3 or 4 elements in the array are equal to [containerID, width, height] or [x, y, width, height]. The rest are element descriptions in format {type: type, <attributes>})
     - callback (function) #optional callback function which is going to be executed in the context of newly created paper
     * or
     - onReadyCallback (function) function that is going to be called on DOM ready event. You can also subscribe to this event via Eve’s “DOMLoad” event. In this case method returns `undefined`.

         * Each letter is a command. There are four commands: `t` is for translate, `r` is for rotate, `s` is for
         * scale and `m` is for matrix.
         *
         * So, the example line above could be read like “translate by 100, 100; rotate 30° around 100, 100; scale twice around 100, 100;
         * rotate 45° around centre; scale 1.5 times relative to centre”. As you can see rotate and scale commands have origin
